Abstract

Objectives

The purpose of this study was to evaluate the properties of the Beck Depression Inventory-II (BDI-2) via the internet.

Methods

Participants included 1967 students of a university. A confirmatory factor analysis was performed to test whether the factor structure of the BDI-2. Convergent validity was assessed by correlating the scores on the BDI-2 with those on other scales.

Results

Two-week test-retest reliability was high (r=0.84) and internal consistency was good (Cronbach's α=0.882). The BDI-2 showed a good criterion validity with strong correlation with Patient health questionnaire 9 (PHQ-9). Factor structure of the BDI-2 was established using the three-factor structure, which explained 43% of the total variance.

Conclusion

The results of the current study indicate that the BDI-2 is an effective and valid scale for evaluation of depression among Korean university students. The findings suggest that the BDI-2 is a promising assessment tool for use in depression and study of depression via the internet.
